•What is the vacuum stability in wide aperture magnets?
Are beam screens needed; if yes, are there new design ideas?
|
V. Baglin, N. Kos | 05.09.2007 | LIUWG#2: Beam-screens are needed. LIUWG#14: preliminary design |
What are the necessary
modifications of D1 dipoles? Is an SC version of D1 more effective
than NC magnets?
|
S. Fartoukh, M. Karppinen, D. Tommasini | 05.09.2007 | LIUWG#2: D1 has to be changed Warm or cold still to be decided. LIUWG#6: warm option. LIUWG#10: cold and warm option. |
| Should the layout be based on two (or more) types of quadrupoles (aperture)? Is modularity (length) advantageous or not? | 05.09.2007 | ||
| How can the heat transfer between the coil and the QRL be improved? What is the preferred design of the coil and magnet structure, and of the heat exchanger? | D. Tommasini, L. Tavian | 05.09.2007 | Discussed at the LIUWG#5. Work on-going. |
| What are the constraints of the cryostat design? What are the “place holders” for the interconnects, for the orbit and other correctors? | V. Parma | 05.09.2007 | Presented at the LIUWG#3 |
| How does the powering and protection infrastructure come into play? | K.H Mess and F. Bordry | 05.09.2007 | Discussed at the LIUWG#7 |
| How can the beam related heat load be minimized in the cold elements? | F. Cerutti, E. Wildner | 05.09.2007 | LIUWG#8 and LIUWG#13: Tungsten liner proposed in Q1. |
